Abdool Karimb aSocial and Behavioral Health Sciences, FHI 360, Durham, NC, USA; bCentre for the AIDS Program of Research in South Africa (CAPRISA), Durban, South Africa (Received 14 November 2013; accepted 20 June 2014) Disclosure, or open communication, by female microbicide trial participants of their trial participation and use of an investigational HIV prevention drug to a sexual partner may affect participants’ trial product usage behavior and contribute to poor adherence. With mixed results from recent microbicide clinical trials being linked to differing participant adherence, insights into the communication dynamics between trial participants and their sexual partners are particularly important. We examined the quantitative association between (1) communication of trial participation to a partner and participant adherence to gel and (2) communication of trial participation to a partner and participant HIV status. An in-depth adherence and product acceptability assessment was administered to the women participating in the CAPRISA 004 trial. Additionally, we collected qualitative data related to communication of trial participation and gel use. Qualitatively, among 165 women who had reported that they had discussed trial participation with others, most (68%) stated that they communicated participation to their sexual partner. Most of the women who had communicated study participation with their partners had received a positive/neutral response from their partner. Some of these women stated that gel use was easy; only a small number said that gel use was difficult. Among women who did not communicate their study participation to their partners, difficulty with gel use was more common and some women stated that they feared communicating their participation. Quantitatively, there was no statistically significant difference in the proportions of women who had communicated study participation to a partner across different adherence levels or HIV status. A deeper knowledge of the dynamics surrounding trial participation communication to male partners will be critical to understanding the spectrum of trial product usage behavior, and ultimately to designing tailored strategies to assist trial participants with product adherence.

    CONTACT: Lisa Rossi +1- 412- 916-3315 (mobile) [email protected] FOR IMMEDIATE RELEASE Results of CAPRISA 004 a turning point for HIV prevention, say MTN researchers conducting VOICE Tenofovir gel used before and after sex reduced HIV by 39 percent, raises bar for VOICE Study testing daily gel use and ARVs for preventing HIV in women VIENNA, July 19 – Researchers who conducted a study testing a vaginal microbicide with an antiretroviral (ARV) drug called tenofovir found its use before and after sex was significantly more protective against HIV infection than a placebo gel among women at high risk of HIV. Results of the study, known as CAPRISA 004, are to be reported at the International AIDS Conference (AIDS 2010) in Vienna and published online by the journal Science. CAPRISA 004 involved 889 women from Durban and a nearby rural community in South Africa, where women are at especially high risk of acquiring HIV through sexual intercourse. Women were randomly assigned to one of two study groups – tenofovir gel or placebo gel with no active ingredient –and instructed to use the study product in a regimen timed before and after sex. At the end of the study, there were 39 percent fewer HIV infections among women who used tenofovir gel before and after sex than among those who used the placebo gel. The study was conducted by the Centre for the AIDS Programme of Research in South Africa (CAPRISA). “This study has established proof of concept that a vaginal microbicide containing an ARV can protect women from HIV. This is an incredibly important achievement for which the CAPRISA team is to be congratulated.

These results were historic. After nearly two decades of research,s thi was the first clinical trial to show that a vaginal microbicide could provide a safe and effective way to prevent sexual transmission of HIV. The gel also provided a 51% protective effect against herpes simplex virus type 2 infection (HSV‐2). The announcement raised questions about the most appropriate next steps: making the gel available to women at risk based on this single trial; planning and implementing additional trials to confirm the results; or waiting for the results of the VOICE (Vaginal and Oral Interventions to Control the Epidemic) trial, another trial of 1% tenofovir gel using a different dosing strategy. To identify priority next steps, WHO and UNAIDS convened a meeting on 25‐26 August 2010 that drew together more than 80 diverse stakeholders from a range of countries.

  • Questions and Answers CAPRISA 004 TENOFOVIR GEL TRIAL
    PAGE 1 Questions and Answers CAPRISA 004 TENOFOVIR GEL TRIAL A randomized, controlled trial to assess the safety and effectiveness of a vaginal microbicide, tenofovir gel, for the prevention of HIV infection among women in South Africa Why did CAPRISA conduct a trial of tenofovir gel for HIV prevention? The CAPRISA 004 study was conducted to establish whether the vaginal use of tenofovir gel is safe and whether it can prevent male‐to‐female sexual transmission of HIV. Specifically, researchers conducted CAPRISA 004 to evaluate the safety and effectiveness of tenofovir in comparison to a placebo gel (a matched gel with no active ingredient) in sexually active women at risk for human immunodeficiency virus (HIV) infection in South Africa. Who conducted this trial? CAPRISA 004 was conducted by a team of South African and American researchers with funds provided by the United States Agency for International Development (USAID) and South Africa’s Technology Innovation Agency (TIA), with product supplied by CONRAD, and with collaborating support from FHI. The principal investigators (study leaders) are Professor Quarraisha Abdool Karim and Professor Salim S. Abdool Karim. When did the trial begin and how was it designed? CAPRISA 004 was a Phase IIb, two‐group, double‐blind, randomized, controlled trial to assess the safety and effectiveness of 1% tenofovir gel, a candidate vaginal microbicide, in 889 sexually active HIV‐ uninfected urban and rural women at risk for HIV infection in South Africa. After undergoing the informed‐consent process, each participant was randomly assigned to one of the two study groups: tenofovir gel or placebo gel.

  • Microbicide Overview
    Microbicide Overview HIV/AIDS ranks among the world’s most devastating diseases because it has spread rapidly and mainly affects young people in their most productive years. More than 33 million people worldwide are living with HIV/AIDS, and 25 million already have died from AIDS (UNAIDS/WHO, November 2009). Each day, about 7,000 more women, men and children become infected with HIV, the virus that causes AIDS. More than 15 million children are without families and homes because of the epidemic, more than 12 million of whom are in sub-Saharan Africa (UNAIDS/WHO, July 2008). Women bear a particularly high burden of the epidemic as primary caregivers for the ill and because of their heightened risk of infection due to biological, economic and social vulnerabilities. Based on the latest comprehensive WHO data, HIV/AIDS is the leading cause of death globally in women 15-44 years of age, particularly in sub-Saharan Africa where the epidemic has hit hardest. Heterosexual sex is the primary mode by which HIV spreads in developing countries. Although a range of prevention strategies exists, they are not enough to stop the spread of HIV — particularly among women. Many women may be unable to persuade their male partners to use condoms or remain faithful. Abstinence is not an option for women who are married, who want children or who are at risk of sexual violence. This is why new prevention strategies that women can use themselves are urgently needed. One such strategy would be microbicides — medical products being developed to protect healthy people from becoming infected with HIV during sex.

  • Background and Rationale
    Phase III Sister Studies of a Microbicide Ring to Prevent HIV: The Ring Study and ASPIRE Summary The Ring Study and ASPIRE are the first large-scale clinical trials to assess whether a vaginal ring containing the antiretroviral (ARV) drug dapivirine can safely and effectively protect against the sexual transmission of HIV when used by women for a month at a time. As sister studies, they represent a major step toward a promising female-controlled HIV prevention method that could potentially provide women with discreet, long-acting protection. Vaginal rings are flexible products that fit comfortably inside the vagina and provide sustained delivery of drugs over a period of time. Vaginal rings are already used in many countries to deliver hormonal contraception. IPM’s dapivirine ring adapts that medical technology as a way to fight HIV. The Ring Study is being conducted by the International Partnership for Microbicides (IPM), which developed the dapivirine ring. ASPIRE – A Study to Prevent Infection with a Ring for Extended Use – is being conducted by the Microbicide Trials Network (MTN) and is funded by the National Institute of Allergy and Infectious Diseases and the National Institute of Mental Health, which are part of the U.S. National Institutes of Health. More than 5,000 women from southern and East Africa will take part in the two studies, which are being conducted in parallel. The dapivirine ring is the first ARV-based product to enter efficacy testing that is intended for monthly use and the first involving an ARV other than tenofovir or a tenofovir combination.
